Bobbi Kristina Brown's aunt, Leolah Brown, publicly claimed on Saturday that her niece's boyfriend, Nick Gordon, is under investigation for "attempted murder" in connection with the 22-year-old's near drowning.

"With all due respect, Nick Gordon is under investigation for attempted murder of my niece Bobbi Kristina Brown," Leolah Brown said in a letter to TV psychologist Phil McGraw, whose CBS talk show Gordon will appear on this week.
